Product Description:

The NDJ-1 Digital Rotational Viscometer is a precision instrument designed for measuring fluid viscosity across a wide range—from 1 to 100,000 mPa·s. This lab-grade device is suitable for testing the flow characteristics of coatings, inks, resins, oils, food products, and adhesives, offering dependable performance in quality control and R&D settings.

With four standard rotors (#1 to #4) and an optional #0 rotor for ultra-low viscosity samples (0.1–100 mPa·s), the NDJ-1 provides multiple speed settings (6, 12, 30, 60 rpm) for dynamic viscosity profiling. Once the measurement stabilizes, the unit automatically stops the rotor, ensuring accurate results with minimal user intervention.

Equipped with RS232 outputs for PC and printer connectivity, the NDJ-1 supports digital data collection and logging. Its compact, durable design and user-friendly interface make it an essential tool for labs, manufacturers, and production lines requiring reliable viscosity control.
